Patented May 6, 1930 UNITED STATES PATENT OFFICE CLAIR D. LAKE .ANDRALPH E. PAGE, OF BINGHAMTON, NEW YORK, ASSIGNOIRS T0 THE TABULATINGMACHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION 0F NEW JERSEYTABULATING MACHINE,

Application led February The present invention covers improvements intabulating machines, more specifically printing tabulators, andparticularly of the type disclosed in copending application, Serial No.639,153, filed May 15, 1923.

These machines, as is well known, analyze perforations in record cardsand after analyzing the perforations may print on a sheet of paper allor part of the data contained on the cards.

It may transmit the data from successive cards to counters, oraccumulators, printing the total of data accumulated from all the cards,or from particular groups of cards if they are arranged in such groups.It may print data from each card and the total of such data for eachgroup of cards. It may also print with each item a designation of thegroup to which the data belongs. ther combinations of similar nature maybe effected.

In the machine described in the above application the recording of groupnumbers was effected hv entering the group number into an accumulatorcounter, then, if it was desired to print this group number, 'thecounter was read by reading devices, and these reading devicescontrolled the type elements of the machine so as to print the groupnumber.

Among theobjects of our invention is the provision of means for printingthe designating number of a group of cards from the first card of thegroup and then suppressing the the paper feed so that when the totals ofthat group are printed they are in alignment on the record sheet withthe group number printed from the 'irst card of the group.

Another object of our invention is the provision of means for printinggroup numbers direct from the cards.

Another' object is to provide means whereby all printing operations areautomatically performed at comparatively slow speed and all non-printingoperations at much higher speed.

Another object is'in provisions for printing the group number from thefirst card of agroup while suppressing the printing of correspondingitems from that Card. and subsc- 5, 1925. serial No. 6,981.

quently printing the total of the group in alignment with said groupnumber.

Another object is the provision of simpler means for printing the groupnumber from each card of a group in alignment with data from that card,and then omitting the printing of said group number when the totals ofsaid item are printed.

Another object is the use of a two speed driving motor the speed ofwhich is automatically varied to provide comparatively low speed forprinting (listing), and a higher speed for non-pril'iting operations.

Other objects reside in the provision of a rearrangement of contacts andcircuits in the machine whereby the use of certain contacts heretoforeemployed may be obviated and whereby other contacts and circuits may beused to perform novel functions which will hereinafter be set forth.

Other objects and advantages will be hereinafter set forth in theaccompanying specification and claims and shown in the drawings which byway of illustration show what is now considered to be the preferredembodiment of the invention.

In the machines described in the previous application group indicatingwas effected by counters, the group number being entered into a counterfor a first card of a group. Thereafter the entering of further groupnumbers c after the first card of a group.

In the machine forming the subject matter of the present application thenecessity for said group indicator cont-acts for each group designatingcolumn is obviated. In place of entering group numbers upon a counter orcounters the group number as taken from the card is arranged to directlycontrol the printing lmechanism of the machine. The feature ofsuppressing the entering of items into the accumulator by the groupindicator contacts after the passage of the first card, is obviated.Group numbers may or may not be entered into the accumulator but, ifentered, these group numbers will be accumulated therein, there being nosuppression of the accunuilation of group numbers.

With our resent machine provision is made for varylng the speed ofoperation when the tabulator is running as a straight tabulator withoutlisting. In other words, while the first card passes through the machineand the group number is being printed therefrom provision is made forrunning the printing attachment at the usual printing or listing speedbecause otherwise the mechanism would be damaged. After the first cardhas passed and the group number is printed the machine automaticallyassumes a higher speed for tabulating the remainder of cards in thatgroup.

In describing the machine two conditions must be considered. The firstor tabulating condition makes records of grou numbers and totals only.The second or listing condition'prints the individual items with thegroup numbers and then prints the totals of the items without the groupnumbers.` If the machine is to be set for tabulating (totaling) itemswithout listing the individual items, i. e., the first conditionmentioned above, so that only totals and group number are printed uponthe record sheet, provision is made for initially printing the groupnumber upon the sheet, as shown in Fig. 10. Subsequently, when-totalshave been accumulated by the machine, these totals are entered upon theIrecord sheet in alignment with the pre viously printed group number,asshown in Fig. 11 of the drawings. l

The second or listing condition has a different operation. Here bothgroup number and J items are printed concurrently, the group numberbeing repeated for each item as shown in Fig. 12. Finally totals areprinted without the accompanying printing of t-he group number.

The instrui'nentalities for bringing these operations about, so farasthe mechanism of the machine'is concerned, are directed particularly toconstructions involving the operation of the listing cam and the partscontrolled thereby, and also the operation of the paper feed.

A clear understanding ofthe present machine will best be had bydescribing the operation of the previous machines upon which the presentinvention is an improvement.

In the previous machines described in the copending application abovereferred to, the rising of the type 266 (Fig. 3), when the machine wasset for listing, was brought about by rocking shaft 305 through theinstrumentality of listing cam 311. When totaling operations were to beeffected, the type were raised by means of total cam 301. In the formermachine the listing cam 311 was its.;

driven at all times when the tabulating machine was operated. If it wasdesired not 1o liz-tt the individual items but to only tabulate, i. e.print totals, provision was made for withdrawing the listing cam rollerfrom cooperation with the listing cam.

l-Iaving now described briefly the previous construction, the modifiedconstruction of the present machine will be described.

Fixed to the listing cam shaft 294, adjacent the listing cam 311, is aclutch disk 500 (Figs. 3, 6 and 7) provided with a notch 501. Listingcam 311 is loose upon the listing cam shaft, and during listingoperations this listing cam is clutched to shaft 294, by the means whichare now to be described.

Pivotally mounted upon the listing cam 311 is a clutch member 502. Theclutch dog 502 is normally drawn into engagement with disk 500 by meansof a spring 503 which, at its opposite end, is fast to a part 504extending over and terminating in a nose 505.

' The clutch dog 502 is provided with a tail or pawl portion 506, whichis adapted to cooperate vwith a shoulder portion '07 upon a rockinglever 508. Lever 508 is also provided with a supplementary pivoted latch509`which allows the member 504 to pass itand prevents backward reboundof the same. For normal listing operations, lever 508 is in thepositionshown in Fig. 6. )Vith the parts in this position clutch dog 502is in engagement with the notch 501'and this couples the listing cam 311to the listing cam shaft 294. Thelever 508 is iixedlymounted upon a stubshaft 510 (see Fig. 23), which shaft is journ'aled vin lugs 511 fixed toa bracket 512 fast to the frame of the machine. It will be understoodthat shaft 510 mustbe rocked in a counterclockwise direction to allowthe clutchdog 502 to engage for listing. This rocking is effected by thelist and i y non-list shaft lever of the tabulator.

. non-list lever of the ta-bulator.

Referring now to Fig. 13: 316 is the list- This lever is fast to a rod317, and around this rod is the usual compression spring 319 heretoforeemployed. As in the previous construction the shaft 317 is provided witha shifter fork 318 (Fig. 17) coacting with cross pins 320 on a shifterrod 300. The arrangement is such that by rocking lever 316 from thetabulating or non-listing position, as shown in Fig. 13. to listingposition (i. e., in the direction indicated by the curved arrow), theshifter rod 300 will be shifted downwardly from the position shown inFig. 13. In place of connecting the slip or shifter rod 300 to thefollower 310, which cooperates with the listing cam 311 as in theprevious construction, the follower 310 is arranged so as to be alwaysin engagement with the cam slot in cam 311. It is entirely free ofcontrol by the shifter rod 300. Upon the end of the shifter rod 300there is provided a beveled nose 513 (see Fig. 19), which nose, when 300is shifted do\\'n\\ardly, separates two fingers 514 and 5,15. in vFig.these. parts are shown in non-separated positimi. Finger 515 (see Fig.6) is fast upon a pivoted arm or lever 516. which in turn is fixed tothe stub shaft 510 previously referred to (see Fig. 23).

The other cooperating finger 514 is integrally disposed on asupplementary arm 517 (Fig. 23), which is substantially similar incontour to 516. Arm 517, instead of being pinned to shaft 510, is loosethereon, and this arm 517 has secured thereto, preferably adjnstably, asupplementary arm 518 (see Fig. 6) carrying upon its end a roller 519adapted to cooperate with a notch 520 in the. listing cam 311. l/Vhenthe shifting lever is in listing position the roller 519 is out ofengagement with the notch 520, as shown in Fig. 6, but when the shiftinglever is in the tabulating position this roller 519 is in engagementwith the notch, in the manner shown in Fig. 7. The purpose of the roller519 is merely to positively locate cam 311 which carries dog 502 so that502 will drop cleanly into slot 501 when shifting lever is shifted tolisting position.

The foregoing has described the means for raising the type 266 duringthe listingy or individual item printing operations. If, after listing,they printing devices are to be operated to take a total a cam 301 onthe so-called total printing'shaft 315 rotates causing elevation of anarm 302 provided with a cam follower. which arm is loosely mounted onshaft 305 (Fig. 14) and is provided with an abutment 303 which isadapted to contact with an adjustmentvscrew 303a carried by the bellcrank lever 304 thus rocking bell crank 304 in a clockwise direction andsimilarly rocking shaft 305. As previously described the rocking shaft305 through arms 306 (Fig. 3)

' is adapted to raise the type 266. To drive the total printing shaft315 the customary l reset motor RM is provided and this, through a shaftand worm 339, drives a worm wheel 340. Fixed to worm wheel 340 is aratchet disk 341 (Fig. 4). Fast on shaft 315 is a socalled printing cam342. Fast to this printing cam is a bar 343 which in turn carries aclutch. dog 344.` The clutch dog overlies ratchet 341'and is normallydisengaged. Engagement of the dog with the ratchet is permitted when thereset clutch magnet 233 is energized. The armature 346 of this magnet ispivoted at 347 and has connectedto it an extended arm 348 which isnotched to engage the tail of the one revolution clutch dog 344. Uponthe energization of magnet 233, latch 348 is elevated and the clutch dog344 drawn by its spring into engagement with the ratchet 341.Subsequently to this engagement the printing cam and printing shaft 315rotate in unison with the ratchet, making one revolution. During thissingle revolution of these parts magnet 233 becomes Adeenergized,permitting latch 5348 .to reengage the clutczh dog and disengage it fromthe ratchet 341. Part 348 vis restored by a spring (not shown) and alsoby block 349 and pin 350. As in the previous construction a rock arm 354(Fig. 4) is provided cooperating with the cam 342,

which rock arm is fixed-t0 a total print shaft the manner described inthe previous application. The rocking of the shaft 355 serves also torock a bail 355a which opens certain contact devices NL1, NL2, etc., fora. purpose which will! hereafter be described.

The foregoinghas explained the general operation when the tabulator isset for straight listing followed by the taking of a total of the listeditems. It will now be assumed that after such a listing run and total istaken it is desired to set the tabulator for straight tabulating,omitting printing of 'items and printing only totals and `group numbers.Figs. 10 and 11 show the report which is printed under these conditions.

The first operation is to shift the tabulator list lever 31,6 from thelisting position to nonlisting or tabulating position. Fig. 13 shows thetabulator non-list lever 316 in so-called tabulating position.- Withthis condition of,

parts the nose 513 (Fig. 19) of the shifter rod 300 will be in theposition shown in Fig.- 19. Consequently inger pieces 514 and 515 willnot be separated. However, upon shifting the shifter lever from theprevious listing position to the non-listing position the finger pieces514 and 515 will have moved from the open position shown in Fig. 6 tothe closed position shown in Fig. 3 and will have permitted arm 508 torock from the position shown in Fig. 6 to that shown inFig. 3 with theend of memberi 508- on top of the shouldered tail of the clutch dog 502.At this time in the cycle the clutch dog is not disengaged from thenotch 501 on disk 500. It therefore follows that uponthe first machinecycle the listing cam 311 will make one revolution and at the completionof'this revolution the dog 502 will be thrown out, assuming thepositionillustrated in Fig. 7. This single revolution of the listing cam311 is utilized for printing the group number on the listing sheet asshown in Fig. 10 of the drawings. As shown in Fig. 11 the totals on therecord sheet are eventually printed in alignment with the previouslyprinted group number. It is therefore necessary to provide means forpreventing the aper feed from the time that the group num er is printeduntil the total printing operation is completed. v

After the listing cam 311. has made one revolution the clutch dog 502 isdisengaged as above explained and remains disengaged until a` total istaken. Upon the taking of a total, magnet 233 is energized actuatingarmagagement with the cam 'dog 344 to permit the machine to take atotal. The armature 3 46 and shaft 347 rock together and the rocking ofshaft 347 causes an arm 352 to rock clockwise (Fig. 5). Arm 352 engagesa pin 621 on an arm 622 fixed on shaft 510 and thus rocks this shaftcounterclockwise thereby rocking arm 508 counterclockwise, releasing dog502 and allowing it to reengage notch 501 to place the parts incondition for listing the following group.

The control of the paper feeding mechanism, its construction andoperation are as follows:

Link 336 at its upper end connects to a- 330. Shaft 305 always operatesthe paper feeding mechanism when it must feed the vaper on the up strokeof the type bars, as or every revolution of cam 311 when listing isbeing performed, an also for one revolution during the first card cyclewhen tabulating operatlons are being performed. As will be shown later,lever 330 actuates lever 334 on the down stroke of the type bars to drawdown on link 336 only during the latter part of a total printing andreset cycle when the achine has been previously set for listing.

When the machine is set for listing the operation of the paper feedingmechanism is as follows: Lever 316 (Figs. 13 and 16) is shifte'dmanually in a counterclockwise direction to listing position and, as rod300 is moved to the right, block 603 (Figs. 8 and 16) ture 346 to liftthe cam latch 348 out of the enlll) attached` rigidly to shaft 317 makescontact with a rejection 604 of latch 337b which is pivotal y mounted at606, and holds latch.

337 in such position that it cannot engage block 337 fixed to member337. Therefore parts 337* and 337b are inoperative while the machineisset for listing and are used as will be later explained for tabulatingonly. While listing, shaft 305 rocks first in a clockwise and then in acounterclockwise 'direction for eac'hrevolution of cam 311 (Figs. 14 and15). At the end of shaft 305 is an arm 338 having at its upper end a pin600. As shaft 305 1s rocked in a clockwise direction this in 600contacts against a shoulder on mem er 337, rocking the unit comprisingparts 334, 333 and 337 about its pivot 601 and drawing down link 336,thus feeding the paper one line space. This occurs while the type barsare being raised.- It will be seen iao iXed in part 333 of that duringlisting operation the paper is fed one line space for each cycle ofoperation of the machine or each revolution of cam 311. On the downstroke of the type bars shaft 305 is rocked in a counterclockwisedirection and allows lever 334 to resume its former position.

At the end of a group of cards which have been listed a total is taken.When the machine takes a total cam 311 comes to a stop and shaft 315 onwhich are mounted cam 301 and gear 328 makes a complete counterclockwiserevolution, as previously described. Cam 301 rocks shaft 305 (Figs. 14and 15) through the same arc as described above for cam 311, so that thepaper is fed the usual one space before printing a total. Early in thesecond half of the total printing cycle shaft 305 completes its rockingcycle and link 336 rises to normal position as parts 334, 333 and 337return to position shown in Fig. 8.

After a total is printed it is desirable to leave a blank space on thepaper before listing the first item of the next group.- The paper is fedthis eXtra space during the last part of the total printing cycle in thefollowing manner: A pin 329 on gear 328 contacts with lever 330 which ispivoted loosely on shaft 305, rocking 330 in a clockwise direction.Lever 330 has an upwardly extending arm 330n to which is connected aslotted link 602. As lever 330 is rocked by pin 329 the lost motion inlink 602 is taken up, stretching spring 608, and link 602 then acts on apin the unit consisting of parts 334, 333 and 337. This rocks the unitin a counterclockwise direction thus drawing down link 336 a second timeduring the total printing and reset cycle to feed the paper an extraspace after total printing. The slot in link 602 and the spring 608above mentioned are necessary to hold lever 330 normally in acounterclockwise position to provide clearance while parts 337% 337D and604 are operative as will be later described.

If it is desired to perform tabulating (as distinguished from listing)operations onthe machine it is necessary to shift lever 316 totabulating position. As has been pointed out, when the machine is setfor tabulating, the listing cam 311 will turn one revolution (during theirst card cycle) starting from the position shown in Fig. 3, beingstopped by the arm 508 after the completion of one revolution. Duringthis revolution the shaft 305 will be rocked and the paper fed one linespace, as above described. But as the shifting of lever 316 totabulating position has moved block 603 out of contact with projection604 block 337a becomes locked in position shown in Fig. 9 by latch 337bactuated by spring 607. The spacing of the paper takes place during theearly part of this cycle. During the same cycle after the spacing hastaken place the printing eii'ected. In the present instance, that is,during tabulating operations, this printing from the first card will beof the group designation number only. As the listing cam'311 is lockedagainst operation at the end of the first card cycle there will be nofurther printing during the c0ntinued operation of the machine until atotal istaken. In the meantime as the operation of the paper feedmechanism has been suppressed-by the latchiiig of block 337a by latch337) the line on which the group number is printed remains in printingposition so that when the total is eventually printed it is on the sameline with the group number, as in Fig. 11. When the total is printedshaft'305 is again rocked in a clockwise direction, this time by cam301, but no movement of 334 or 336 takes place on this up stroke of thetype bars due to lever 337 being held by block 337 and latch 337". .Theresult is that paper is not fed at this time and the total is printed onthe same line as was the indication number during the first tabulatingcycle. Near the end of the revolution of shaft 315. after shaft 305 hasreturned to its normal position, pin 329 on gear 328 makes contact withlever 330 and causes it to rock about pivot 305 in a clockwisedirection, the slot in link 602 attached to its upper end allowing it tomove freely. As lever 330 nears the end of its clockwise rockingmovement its upward projection 330a acts against projection 604 of latch337", releasing block 337a and allowing 337 and attached members,including link 336, to resume normal position, with the shoulder 0f 337against pin 600. As soon as pin 329 has passed the end of lever 330,spring 608 draws lever 330 to its normal position. It will be `observedfrom the above that lever 330 has two entirely different functions toperform, depending upon whether the inachine is set for tabulating orlisting.

y Referring now to Figs. 20 ,and 21, the parts show the usual groupindicator and automatic control unit. As in previous machines shaft 398is rotated in unison with the tabulator shafts during tabulatingoperations and arm 404 is rocked during resetting and total printingoperations. 92 is the group indicator magnet. Upon the energization ofthis magnet latch 417 is attracted releasing arm 418 fast to bail 416which thereupon rocks clockwise under the influence of spring 419.Cooperating with bail 416 are three contacts G11, Gl3 and GI8 insteadofthe ten group indicator contacts heretofore employed. Contacts G11 andG13 are normal open contacts and GI8 are closed so that upon the rockingof bail 416 un'der control of inagn'et 92 contacts GI8 will open and G11and G13 will close. This action'occurs at or towards the end of thefirst card cycle of a group. Bail 416 is restoredV in an anticlockwisedirection during the reset and total printing cycles by means of arm 404and shaft 400.

Contacts 71 and 73 are the usual automatic control contacts which arecontrolled .by automatic control magnets' 72. These parts being the sameas in previous machines require no detailed description.

The machine is also provided with a gear transmission 257 (Fig. l) whichis shifted when the tabulator is set for listing to drive the parts atthe low printing speed. The transmission is provided with contacts 250(shown on the circuit diagram) and which are closed as in the previousmachines when the transmission is set to drive the machine at reducedspeed.

' Referring now to the diagram views (Flgs. 26a and 26h), 50 designatesa stack of record cards which are adapted to be advanced one at a timeby means of a picker 51 into engagement with feed rolls 52. The feedrolls ultimately advance the cards to the discharge stack in the usualmanner. Rolls 52 are driven by gearing generally designated 53 which inturn is driven by a tabulator motor TM through the usual magneticallycontrolled clutch 54. This clutch is controlled by clutch magnet 55.Cards are advanced past upper brushes 55 and contact blocks 56, andthereafter past lower brushes 59 and contact blocks 60. The upper andlower brushes are respectively carried by common bars 57 and 58. Upperand lower card levers 61 and 62 are provided, which card levers arerespectively adapted to close upper card lever contacts 63b and lowercontacts 63a and 64a. From the upper and lower brushes cabled wires 65and 66 are shown leading to plug sockets on the tabulator plugboard 254.Sockets 67 are for the upper brushes and multiple sockets 68 are for thelower brushes. On the plugboard there are also sockets 69 which areconnected directly to the counters and supplemental sockets 70 which aredirect- Y ly connected to the printing magnets without having anycounter magnets associated there'- with. On the upper end of theplugboard there is shown a circuit diagram of the automaticcontrol'unit. When certain columns are to be used for automaticcontrolling, plug connections are inserted between sockets 67 andsockets 670 of the automatic control unit. From socket 680 of thecontrol unit plug connections may be made between 680 and 68. From anyplug sockets 68 connections may be made as desired to 69 and 70. It willbe understood that the automatic control can be plugged in any desiredcolumns, also that the automatic control may be plugged from 680 to68tand thence to 70 without plugging up corresponding plug sockets 69.In nthis way the control number may be printed on the extra listingbanks without sacrificing counter capacity when this is done. Theautomatic control unit is the same as heretofore em-` .of a

ployed in machines and requires no detailed description. There is anautomatic control circuit 74 which extends serially through all contacts7 3 of the control unit, as in the previous machine.

In the statistical work handled by tabulating machines the record cardsare usually arranged in groups, each card of the group bearing adistinguishing number which serves to identify that particular group,and it is customary for the machine to indicate the group number of eachgroup for purposes of identification.

In the machine described in the previous application this groupindicating was effected by the regular tabulating counters oraccumulators, the group number being entered into a counter from thefirst card of'each group. Thereafter the entering of further groupnumbers into the counter was suppressed by means of group indicatorcontacts which opened up after the passage of the first card.

In the present machine the use of group indicator contacts is minimized.In place of entering group numbers upon a counter or counters the groupnumber as taken from the card'is arranged to directly control theprinting mechanism of the machine. The feature of suppressing theentering of items into the accumulator after the passage of the firstcard is obviated. Group numbers may or may not A cu be entered into 4theaccumula-tor, but, if entered, these group numbers will be accumulatedtherein, there being no suppression of the accumulating of groupnumbers. 4

When this machine is used as a straight tabulator, without listing theitems, it is run at a comparatively high speed but while the first cardof each group is passing and the group number is being printedtherefrom, provision is made for running the printing attachment at theusual (slow) printing or listing speed, otherwise the mechanism would bedamaged. After the first card has passed and the group number has beenprinted the machine automatically .resumes its higher speed fortabulating the remaining cards of that group.

In connection with the printing of the group number in straighttabulating (nonlisting) operations provision is made for printing thegroup number upon the' record sheet only upon the passage of the firstcard group. Thereafter the 'normal paper feed is suppressed and whenultimately the total of that group is printed it is printed in alignmentwith the previously printed group number. Thereafter the normal paperfeed is resumedto space the paper to position to receive the new groupnumber imprint of the lnext group.

When the machine is set for listing, the

group number is printed concurrently with.

each listed item of that group. The group number is not repeated whenprinting totals of listed items. The printing of all totals is effectedat proper printing speed by the reset motor.

Referring now to Figs. 13, 17 and 18, with the resistance controlledmotor type of con- 316 shifted to listing position contacts X1.

will be opened and contacts X2 will be closed.

Fig. 18 shows other cooperating contacts which come into action when theshifter lever is in listing position. These contacts Z1 and Z2 arearranged to be both closed when the shifter lever is'in listing positionand both opened whenthe shifter lever is in tabulating position.

Referring now to Figs. 24 and 25, shaft 355 which, aspreviouslyexpla'ined, rocks only during totaling operations, Visprovided with a depending insulating bail 355, which bail is arranged tonormally hold open a number of non-list contacts NL1, N112, NL3, NL1 andNL5. Upon total-taking, shaft 355 lrocks clockwise (Fig. 24) and allowslall of these contacts to close. The purpose of these contacts is toclose circuits to the printing magnets of the various individualcounterswith which they cooperate and thereby allor a total to be printed of theamounts standing on such counters, except when such counters carry asummation of group numbers, inwhich case other means are provided forpreventing the printing of such amounts.

1n the diagram, Figs. 26aand 26", the tab ulating motor TM is providedwith a resistance 625 which can be manually adjusted by means of taps626 to shunt out portions of the resistance as desired. l

Referring to Fig. 26at it will be noted that with contacts T1 and G13both open the resistance 625 will be in the armaturev circuit of themotor TM. With such resistance in cir cuit with the armature the motorwill rotate at a comparatively slow speed This is the speed which isused `for printing the group number from the first card. 1t is, however,desirable that all resistance be cut out of the armature circuit atstarting to give the motor sufficient torque to start the machine. Howthis is done will be apparent from the diagram. The diagram shows theparts in condition for starting. Here cam contact T4 mounted in the camboX of the tabulator is shown closed. This cam contact being in circuitbetween binder posts 16`and 17 cuts the resistance 625 entirely out ofcircuit and allows thetabulator motor to start with full current andfull torque- Immediately after the motor has started cam contact T1opens cutting resistance 625 into circuit. 1nasmuch as durin the firstcard cycle of a group cam contact 13 is open, themotor now continues inoperation until the first card cycle is completed whereupon cam contactG13 closes, thus shunting resistance 625 again out of circuit andpermitting the motor to operate at a high tabulating speed. Due to thefact that the current through the. motor is materially cut down for thefirst card cycle the current through the clutch magnet is so small thatit does not hold its armature when contact C4 was made. To obviate thisdifficulty contact G11 is provided in circuit with cam contact C4. Camcontact G11 remains open during the first card tabulating cycle only andthus suppresses any action of cam contact C4 with respect to clutchmagnet 55 during this card cycle. On subsequent card cycles after thegroup number is printed-cam contact G11 closes and is ineifectivepwithrespect to cam contactC4.

Cam contact T1, opens av'short time before the end of the cycle and ifrunning at normal speed the motor TM has sufficient momentum toA bringthe kmachine to home or D position. With motor speed reduced as aboveforprinting this momentum is not sufficient to bring the tabulator partsto home position, if the tabulator is operating on one card group,- theonly occasion -when thepmotor is called upon to stop while running slowunder control of resistance. 625. 1n order to bring the tabulator tohome position under these condithrough cam contactL4 through motorcontrol relay contacts 130, through stop key contacts 87a and back tobinder post 9. Cam contact L4B is arranged to make before cam contact T1opens and to break at a slightly later point in the cyclethus'permitting the motor TM to continue in operation for a suliicientlylonger period of time to enable it to reach home position whentabulating on one card group. Cam contact L1 is operated from listingshaft 294 which is in operation at all times when tabulating and listingor when printing the first group number.

1n the event that the tabulator is stopped by the emergency stop key 87a when running at slow speed during the first card cycle it is desirablethat means be provided for bringing the tabulator to home position. Forthis purpose a supplementary circuit 627 is providedextending to camcontact L4 and`connecting to a bottom contact of the emergency stop key871. With emergency stop key depressed the tabulator will come to homeposition in the manner previously described.

' Referring now to Fig. 26a, contacts 250 are the usual transmissioncontacts (not shown) which are o ened when thetransmission 257 (Fig.1)fis'1n high speed position for tabulating and which are only closedwhen the transmission is in low speed position for list- 1n0.

lContact X1 is in the circuit between binder posts 10 and 12 and thiscontact in addition to operating with contact 250 to compel thetransmission to be shifted to slow speed position for listing also haveother purposes now to be described. Contact 250 is in a line eX- tendingfrom binder post 10 to binderpost 12 which also includes Contact Z1.VV'hen the list-non-list lever (Fig. 13) is shiftedfrom listing positionto tabulating position or vice versa, there is a period of time in theshifting of such lever when both contacts X1 and Z1 will be opened. Thisopening of contacts X1 and Z1 during shifting operations is utilized tocompel a resetting operation.l

Assume that the machine has been run with a listing setting and hasstopped at the end of a card group the condition of the parts will be asshown in Fig. 6. If then the listvnon-list lever 316 is shifted theparts will assume the-position of Fig. 3. If now the machine wererestarted on the next card group the Contact GI3 of the circuit diagramwill not have reopened because there has been no intervening reset cycleto open them. Under such conditions the machine vwould restart andoperate the listing mechanism under high tabulating speeds. To preventsuch improper operation cert-ain circuit controlling connections areprovided which will now be described.

Referring to the diagram, 84 is the magnet controlling motor relaycontact 130. By providing means for deenergizing 84 during a shiftingoperation land by compelling a sub' sequent resetting operation of themachine before relay 84 can be reenergized, the aforesaid objectionablestarting at high speed is prevented. Referring to the diagram, circuitcircuit 628 is provided from the armature of relay 91 extending throughcam contact P3 to one side of cam contact C1. The only way in which 84and 91 can be energized is through wire 629 to binderv post 9, thencethrough binder post 10 to 12. By timing cam contact P3 so that this camcontact is open when the machine is in stopped position, and inasmuch asduring shifting operations both contacts X1 and Z1 are opened at thesame time there will be no path for current to How from left side ofline through 84 and thus restarting of the machine will be preventeduntil current can be again applied to 84 after contact P3 is closed.Contact P3 is on total printing shaft 315 and is only operated duringresetting and tota-l printing cycles.

Inasmuch as transmission 257 is used when straight listing is performedmeans must be provided for keeping resistance 625 from having anycontrol of the mot-or during listing with the transmission shifted tolisting position. Cam contact Z2 is employed for this purpose. This camcontact closes circuit Asame card cycle current would be 630 whichextends to a wire 631 leading to group indicator controlling magnet .92.Thus when the list-non-list lever 316 is shifted to listing position camcontact Z2 will be closed, energizing 92 and causing contact G13 to betripped and closed thus shunting out resistance 625. This contact willremain closed as long as listing continues and is only reopenedupon thenext resetting operation. Then after it is reopened on the nextresetting operation it is again immediately closed inasmuch as 92remains energized.

As previously explained, when running under tabulating conditionscontact GI3 closes after the first card cycle. The closing of thiscontact is effected by means of group indicator controlling magnet 92being energized. This magnet when the machine is running undertabulating conditions has its circuit 631 closed by cam contact La whichcloses a circuit to G32 just at the end of the first card cycle. Camcontact Ls is on the listing shaft 294 of the machine.

Inasmuch as in printing the group number from the first card of a groupthis group number is printed directly from the card, provision must bemade for supplying current to the printer magnets during this rst vcardgroup printing cycle of the machine. Referring to Fig. 21 contact GIS,as previously explained, is made for the first card cycle and breaksthereafter, being retained broken until a new group is tabulated. Thiscontact as shown in Fig. 26b is in a line 633 extending between binderpost 13 and binder post 8. The purpose of contact G18 is to supplycurrent to the printer magnets which are correlated with the countermagnets if it is desired to group indicate on the columns in theprinting section of the machine which are coordinated with the counters.In Fig. 26b 102 are the printer magnets. These printer magnets areconnected to common bars 116. Bars 116 through wires 104 connect to thenon-list contacts NL1, NL2 and NL3, etc. Contacts N 1, 2 and 3, etc., aspreviously explained, are open at all times except when a total isprinted. Therefore with these contacts open it would be impossible toprint the group numbers on the printer mechanism corresponding to theseparticular counters. If it is desired to print the group number on thefield of the record corresponding to, say, bank N o. 3, a switch 634would be iirst closed around the non-list contacts N L1. With thisswitchl closed during the first card cycle and with contact GIs closedduring the supplied to common bars 116 from binder post 13, contact G18,wires 633, upper contacts P1 now closed, line 635, contact Ll)1 nowclosed, through switch 634 to common bar 116. In this way the magnets102 are provided with a return path for the current which, as will beunderstood, is a secondary circuit which has been completed by theenergiation of counter magnets from the brushes and the subsequentclosing of contact 100. This counter magnet circuit will be traced forone column from left side of line, wire 82, through wire 101, contact99, counter magnet 98 to plug socket 69, thence by plug connection toplug socket 68, thcnc(` through wire 65 to lower brushes. `When an indexpoint perforation passes the lower brushes 59 current flows throughthese brushes, wire 95, cam contacts T2, T3, to binder post 13, wire 94,lower contacts P* now closed, binder post 11, through wire 636, to lowercard. lever contacts 64",' to the relay point of relay 85, thence to camcontact T1, to binder post 9, through P5, binder post 10, contact X1, tobinder post 12 on other side of line 83. The energization of magnet 98closes contacts 100 and sets up a supplemental printing circuit asfollows: from left side of line 82, through 101, contacts 100, printermagnet 102, common bar 116, wire 104, nonlist switch 634, and throughthe circuit previously traced through GIB to left side of line. It willbe understood that switches 634 are only closed on the particular bankwhich is to be used for printing group numbers. If the tabulator is setfor listing all the switches 634 will be closed on all banks in which itis desired to list individual items. The same l-applies if particularbanks are to be used for indicating group numbers whenlisting. If it isdesired to print only totals on particular banks, corresponding switches634 can be opened. If the machine is set for listing, contacts X2, whichare closed with such a setting of the list-non-list lever, complete thecircuit to the printer magnets atvall times, acting similarly to contactG18 except that it does not open up after the first card cycle.

Contacts LPl, LP2, LPS, etc., are driven and actuated by or from totalprinting shaft 315 (Fig. 5) The purpose of these contacts is to breakthe circuit to the printing magnets at the end of the printing part ofthe reset cycle. They function similarly to contact-s P2 and P3 in theLake application above referred to. Upper contact P2 whose cam is on thetotal printing shaft 315 is used to prevent certain objectionable backcircuits during the total print cycle. The upper contact opens at thebeginning of a total print cycle and closes at the end of such cycle.The lower cam contact P2 closes at the beginning of the total printcycle and opens at the end of the cycle. During total printing, currentto the printing magnets 102 is supplied from right side of line 83,through non-total print switch 237, which switch has previously beenclosed. If it is desired to suppress the printing of totals non-totalprint switch 237 is opened. If a particular bank of the machinecorrelated to a counter is used for printing group numbers it will beunderstood that those group numbers will be accumulated in that counter.Obviously it is not usually desirable to print an accumulation of groupnumbers. Therefore, if group numbers have been indicated on a.particular counter bank, after the group has been completed, it isnecessary that the accumulated group number be not printed. T his iseffected by merely opening up zero button contact 128 by Zero buttonlever 129. With zero button shifted the counter will not be cleared butneither will the accumulated group number be printed. Before thisparticular counter can subsequently be used for accumulating purposes itis necessary t-o lclear out the accumulation on group numbers from theparticular counter. This is done by a resetting operation prior to whichresetting the switch 237` is first opened to prevent the accumulation ofgroup numbers from being printed on the record sheet. In the embodimentof the circuit diagram shown in Fig. 26a the lower card lever contacts64"L and 63 correspond to card lever contacts 64 and 63 in the previousLake application heretofore referred to with the exception that they areboth operated from the lower card lever in place of operating one fromthe upperand one from the lower as heretofore. The purpose of lower cardlever contacts 63a arid 64a is to keep the machine running so long ascards are passing through the machine. The purpose of the single uppercardlever Contact 63b which is in one of the branches 7 4 of theautomatic control circuit is to open the control circuit 7 4 after thepassage of the last card through the upper brushes. This will insurethat the cam contact L4 properly comes into action to bring the'machineto the D (home) position. As previously explained Ll is only operated tobring the machine to home or D position when fthe relays 91 and 84(which'control contacts "130) are deenergized. With the last group.consisting of a single card, relay 91 woul be held energized if contact63b were not provided. This contact under these conditions` will openand deenergize 91 allowing L4 to function in a proper manner.

Cam contact T5 is vopened at D position and is closed at all other timesin the tabulating cycle. This contact entirely cuts olf the current tothe upper brushes whereby they preios vent blowing of fuses duringplugging opin alignment with said card group designations on said recordsheet.
